6 Unit 1

Matter and Energy

TermDefinition
solid has a definite shape and a definite volume because particles are packed very closely together; can be hard and brittle or flexible, smooth and heavy or sharp and light
liquid has a definite volume but no shape of its own because particles are always in contact with each other but can move more than a solid
gas has no definite shape or volume because particles do not remain in contact with one another and move to fill all available space
thermal energy the total kinetic and potential energy of all particles in an object or substance; increase by adding heat
temperature a measure of the average kinetic energy of the particles in an object or substance; measured in degrees Celsius or degrees Fahrenheit
melting point the temperature at which a substance changes from a solid to a liquid; the same as the freezing point
freezing point the temperature at which a substance changes from a liquid to a solid
boiling point the temperature at which a substance changes from a liquid to a gas
thermal energy The total kinetic and potential energy of all the particles of an object
conduction The transfer of thermal energy from one particle of matter to another
convection Transfer of thermal energy by the movement of a fluid
convection current the movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another
radiation the transfer of energy by electromagnetic waves
conductor A material that allows electric charges to flow or conducts heat well
insulator a material that does not conduct heat well
condensation the change in state from a gas to a liquid
evaporation the process by which molecules at the surface of a liquid absorb enough energy to change to a gas

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
